Abstract: Based on the T-S model, it researches the problem with delay-dependent robust fuzzy control for stochastic nonlinear systems with parameter uncertainty and timevarying delay. According to theories and approaches of Lyapunov stability, Schur complement lemma，Jensen integral inequality and free weighting matrices and Ito formula, the system controller was designed for all admissible uncertainties by using the PDC method. When the LMIs were feasible, the desired state feedback controller could be constructed. Finally, the numerical example was given to demonstrate the effectiveness of the method.
